Well, it uses the term 'applied score' or some form or that term several times throughout the explanation of the system. It shows a 10 point scale of each skill level ranking (2 - 7) and discusses win percentages and innings played. I'd be happy to send it to you for your opinion. But more to the point - what CAN you tell us? This is AZBilliard, as far as we know your given name is APA Operator, so you're reasonably annonymous here. I understand you can't say , "I'm Joe, and I'm the APA League Operator in Alabama and this is how it works..." But really, how's it work?
I missed this reply earlier, so I'll answer it now. Though I'm reasonably anonymous to most people here, there are actually a few who know who I am, people I know personally and trust to keep that information confidential. There are also APA League Operators who read this forum but don't participate. I'm pretty sure many of them also know who I am. So the answer to your first question is "I can tell you nothing about what's under the hood." I can't even confirm or deny any guesses, speculation, or information you may have come across somewhere else, because even a denial gives you SOME information.
To answer your second question, here's how it works: :banghead:
